            1. Electrical And Acoustical Measuring Condition

            Recommended setting
                 

            1. Frequency Response

             

            1. Surface mounting condition

            5.1 Reflow soldering
                   Recommendable reflow soldering condition is as follows.
                    
                   Note: (1) In automated mounting of the SMD sound transducers on PCB, any bending, expanding
                   and pulling forces or shocks against the SMD sound transducers shall be kept minimum
                   to prevent them from electrical failures and mechanical damages of the devices.
                   (2) In the reflow soldering, too high soldering temperatures and too large temperature
                   Gradient such as rapid heating or cooling may cause electrical failures and mechanical
                   damages of the devices.

            1. Reliability Test

            After any following tests the part shall meet specifications without any degradation in
                   appearance and performance except SPL. SPL shall not deviate more than -10 dB
                   from the initial value

              1. Ordinary Temperature Life Test

            The part shall be subjected to 96 hours at 25±10℃. Input rated voltage
                   Resonant frequency, 1/2 duty Square wave.
                   6.2 High Temperature Test
                   The part shall be capable of with standing a storage temperature of +80℃ for 96 hours.
                   6.3 Low Temperature Test 
                   The part shall be capable of with standing a storage temperature of -30℃ for 96 hours.

              1. Humidity Test

            Temperature:+40℃±3℃   Relative Humidity:90%~95% Duration: 48 hours
                   and expose to room temperature for 6 hours

              1. Temperature Shock Test

            Temperature:60℃ /1hour→ 25℃/3hours→-20℃/1hour→ 25℃/3hours (1cycle)
                   Total cycle: 10 cycles

              1. Drop Test

            Standard Packaging From 75cm(Drop on hard wood or board of 5cm thick,
                   three sides, six plain.)

              1. Vibration Test

            Vibration:1000cycles /min. Amplitude:1.5mm, Duration: 1 hour in each 3 axes

              1. Reflow Test

            Use recommendable reflow soldering condition (as shown in 5.1)
                   (1) No abnormality should be found after reflow
                   (2) Good soldering to meet soldering requirements

             

            Note:
                   As this product is not protected from foreign material entering, please make sure that any foreign materials (e.g. magnetic powder, washing solvent, flux, corrosive gas) do not enter this product in your production processes. The functional degradation (e.g. SPL down) may occur if foreign material enter it.
